Pneumonia pneumonia is a lung infection that can be caused by different types of germs, most commonly viruses. This article of pneumonia. http://kidshealth.org/parent/infections/bacterial_viral/pneumonia.html

Extractions: Pneumonia is a general term that refers to an infection of the lungs, which can be caused by a variety of microorganisms , including viruses, bacteria, and parasites. Often pneumonia begins after an upper respiratory tract infection (an infection of the nose and throat). When this happens, symptoms of pneumonia begin after 2 or 3 days of a cold or sore throat. Symptoms of pneumonia vary, depending on the age of the child and the cause of the pneumonia. Some common symptoms include: Sometimes a child's only symptom is rapid breathing. Sometimes when the pneumonia is in the lower part of the lungs near the abdomen, there may be no breathing problems at all, but there may be fever and abdominal pain or vomiting. When pneumonia is caused by bacteria, an infected child usually becomes sick relatively quickly and experiences the sudden onset of high fever and unusually rapid breathing. When pneumonia is caused by viruses, symptoms tend to appear more gradually and are often less severe than in bacterial pneumonia. Wheezing may be more common in viral pneumonia.

Extractions: FO-05750 1993 To Order Ovine Progressive Pneumonia in Sheep Cynthia B. Wolf Ovine progressive pneumonia is a viral disease of sheep in North America. Common synonyms for this disease are progressive pneumonia and OPP. The OPP virus closely resembles Maedi-Visna, which is a similar slow virus (retrovirus) found in other parts of the world. The OPP virus can cause disease with any of the following signs: severe and progressive weight loss, labored breathing or pneumonia, paralysis, swollen joints associated with lameness, and palpably hard, unproductive udders. However, most infected sheep never show clinical signs of disease. Once a sheep is infected with the virus, that animal stays infected for its lifetime and serves as a carrier even in the presence of high levels of circulating antibodies. Unlike some viral diseases, the presence of antibodies is not indicative of immunity.

And can you really catch it from splashing in a rain puddle or hanging out in a soaking-wet sweatshirt? Keep reading to learn about pneumonia, what causes it, and more. What Is Pneumonia? Pneumonia (say: new- mo -nya) is an infection of one or both lungs . To know what that means, you have to know something about lungs and what they do. When you breathe in, air rich with oxygen is pulled into your lungs. Healthy, normal lungs allow the oxygen you breathe in to pass through the air chambers of the lung called alveoli (say: al- vee -oh-lie) and into the blood. The oxygen then travels in the red blood cells to all parts of the body. When you have pneumonia, fluid blocks the alveoli in your lungs. This makes it harder for oxygen to enter the lungs and pass through to the blood Pneumonia can happen to people at any age, from tiny babies to older people. Most people with pneumonia will feel sick. They usually have faster breathing than usual - or difficulty breathing - and may also have chest pain and

Extractions: Pneumonia June 2001 WHAT IS PNEUMONIA? Pneumonia is an inflammation of the lung caused by infection with bacteria, viruses, and other organisms. Pneumonia is usually triggered when a patient's defense system is weakened, most often by a simple viral upper respiratory tract infection or a case of influenza. Such infections or other triggers do not cause pneumonia directly but they alter the mucous blanket, thus encouraging bacterial growth. Other factors can also make specific people susceptible to bacterial growth and pneumonia. Defining Pneumonia by Locations in the Lung Pneumonia is sometimes defined in one of two ways according to its distribution in the lung: Lobar Pneumonia (occurs in one lobe of the lung). Bronchopneumonia (tends to be patchy). [For a description of the lung , see Box The Lungs. Defining Pneumonia by Origin of Infection Pneumonia is often classified into two categories that may help predict the organisms that are the most likely culprits. Community-acquired (pneumonia contracted outside the hospital). Pneumonia in this setting often follows a viral respiratory infection. It affects nearly 4 million adults each year. It is likely to be caused by

Aspiration Pneumonia [General] Pneumonia: An acute infection of lung parenchyma including alveolar spaces and interstitial tissue. Pneumonia (pneumonitis) may affect an entire lobe (lobar pneumonia), a segment of a lobe (segmental or lobular pneumonia), alveoli contiguous to bronchi (bronchopneumonia), or interstitial tissue (interstitial pneumonia). These distinctions are generally based on x-ray observations. (See also discussions of tularemic pneumonia under Tularemia and pneumonic plague under Plague in Ch. 157 and rickettsial pneumonia under Q Fever in Ch. 159; pneumonias in newborns are discussed in Neonatal Pneumonia in Ch. 260.) Etiology and Epidemiology In the USA, about 2 million people develop pneumonia each year and 40,000 to 70,000 die; it ranks sixth among all disease categories as a cause of death and is the most common lethal nosocomial (hospital-acquired) infection. In developing countries, lower respiratory tract infections are usually the major cause of death, or they rank second only to infectious diarrhea. Streptococcus pneumoniae is the most common. Other pathogens include anaerobic bacteria

Extractions: A new clinical prediction model can help clinicians determine the most appropriate care for newly diagnosed cases of community-acquired pneumonia (CAP). The model recently was announced by a team of researchers supported through a grant from the Federal Agency for Health Care Policy and Research (AHCPR). The model stratifies patients into risk categories based on their medical history, physical examination findings, and a limited set of laboratory and radiographic results. This is a major breakthrough, since the factors used to predict risk are clearly defined and can be readily assessed at the time of patient presentation. The model also predicts other important medical outcomes, such as length of hospitalization, admission to an intensive care unit for respiratory failure or hemodynamic compromise, and time to usual activities. About 600,000 of the 4 million Americans who develop CAP each year are hospitalized. Because of a lack of evidence-based admission criteria and the tendency to overestimate the risk of death, many low-risk patients who could just as safely be treated as outpatients are instead admitted for more costly inpatient care. The investigators made projections from a prospective cohort study of 2,287 CAP patients in Pittsburgh, Boston, and Halifax, Nova Scotia. They suggest that if the model had been used, 26-31 percent of the patients who were hospitalized for care could have been treated safely as outpatients, and an additional 13-19 percent could have been hospitalized only briefly for observation. The investigators validated the model for accuracy and general applicability with data on over 50,000 CAP patients in 275 U.S. and Canadian hospitals.

Pneumonia | Treatment If you develop pneumonia, your chances of prompt recovery are greatest under certain conditions There is no effective treatment yet for viral pneumonia. http://www.lung.ca/pneumonia/treatment.html

Extractions: Prompt treatment with antibiotics almost always cures bacterial and mycoplasma pneumonia, and a certain percentage of rickettsia cases. There is no effective treatment yet for viral pneumonia. The drug or drugs used are determined by the germ causing the pneumonia and the judgment of the physician. The drugs lower body temperature within a day or two and produce a dramatic recovery. After temperature returns to normal, medication must be continued according to physician's instructions, otherwise the pneumonia may recur. Relapses can be far more serious than the first attack. Besides antibiotics, patients are given supportive treatment: and in the case of mycoplasma: anything that can produce and maintain in the patient the best possible conditions for recovery.
